So.
This is my own idea for Nikana Prime build (works on every Nikana-Stanced weapons (Nikana, Nikana Prime, Dragon Nikana and Skiajati).
It's universal Crit-Combo-based badass build that I created for [Excalibur Umbra] with [Daikyu] with Amalgam mod [Amalgam Daikyu Target Acquired] to make it solo carry nearly everything (on Survival Arbitration I could survive solo just by cutting down mobs)

UPDATED: I decided add more nature dmg to this blade. Myslef Im using Riven mod but if you have no Riven for Nikanas You can easly go this build. [Primed Fever Strike] is highly recommended.
But! You can use different types of dmg. Any you need atm. Primed FS is good like for me cuz you can easly go in Corrosive and Viral. [Nikana] works Good enough on Steel Path missions like Extermination, Survival, Capture or Excavation.
Build is also nice for [Nekros] due to tons of Slash dmg (fast and efficient farm)
With Gladiators [Rush] and Naramon Focus tree you can keep your Combo easly above 0 even without fighting. Ofc. you can also use Gladiators Might what makes it even stronger for all-time-fight
UPDATE after nerfs: Build still works on both Low lvls and Steelpaths. Red crits arent promised but still this build is most efficient I;ve made. [Blood Rush] nerf made it bit weaker but still playable and good. Also now Glad Might works better
